1 GENERAL

1.1 Scope of the manualThis manual provides the essential information needed byusers of PZ capping valves. If you require further informa-tion on actuators and instrumentation, see the separateinstallation, maintenance and operation instructions for thevarious models.

1.2 Valve constructionThe PZ is a capping valve designed for use in batch digest-ers. The valve is fitted to the digester from the lower bodyflange.

The upper body half has a metal seat into which the ball ispressed by a mechanical tilting device when the digester isnot pressurized. The tilting device is pre-tightened duringinstallation, and no adjustments are required during opera-tion. The pressure of the digester further tightens the sealprovided by the tilting device.

The mounting holes for the chip feeding chute are in thetop flange plane of the valve.

The ball and stem are integrally cast. The hard-chromed ballsurface ensures low friction and high corrosion resistance.The full-bore ball and the flow port’s liner insert allowsmooth passage of the chips.

Optionally there are electrical or mechanical interlockingdevices available.

The electrical interlocking device consists of pressure trans-mitters (2 pcs.), relays, solenoid valves and limit switches.

See the application report no: 2611/01/02en * 12/2011,Safety interlocking system, "ACC".

The mechanical interlocking device B1CP is based on aspring-return cylinder which operates a lever inside theactuator. This lever locks the valve in the closed position.

These devices prevent the valve from opening while thedigester is pressurized.

1.3 Valve markingsThe valve has an identification plate (Fig. 2). The upperbody half is marked with the pressure rating, nominal size,batch number, body material and manufacturer’s code.

Identification plate markings are:

1. Body material2. Ball material3. Stem material4. Seat material5. Maximum operating temperature6. Minimum operating temperature7. Maximum shut-off pressure differential/temperature8. Type designation9. Valve manufacturing parts list no.10. Pressure class

1.5 Valve performanceActuators are factory set for proper opening times.

1.5.1 Operation timeDuring start-up or other exceptional circumstances, cap-ping valves must meet extreme conditions where pressure,impurities and high operational velocities can cause mate-rial damages (ball / seat ring). Therefore PZ capping valveshave a recommended minimum operation time for 90°rotation as listed:

Adjusted operating times are factory preset values, obtainedwith restrictor valves installed in actuator air supply linesbetween solenoid valve and actuator cylinder.

1.5.2 Vacuum during cookingIn modern cooking processes there can be sequenceswhere digester vessel operates below atmospheric pressureie. in vacuum conditions.

In such cases it is recommended not to exceed 30 kPa (0.3bar) vacuum with PZ capping valve.

If higher values are expected, please contact the manufac-turer. See also Section 1.5.5.

1.5.3 Valve tightnessAll PZ capping valves are factory tested to fulfill ISO 5208rate D leakage test.

Corresponding leakage values, tested with water1.1 x nominal pressure.

1.5.4 Additional arrangementsDuring normal sequences of cooking the PZ-series lockedscraping metal seat keeps the hard chrome plated ball sur-face clean ensuring long lasting tightness and smoothoperation. However, in practice, it is difficult to totally pre-vent chips, sawdust, dirt or any other contaminants fromadhering to the ball surface, particulary during the cookingsequence (temp about 175 °C / 347 °F), causing possibleball surface damages.

Metso realizes that some mills may require a water wash/spray to the ball surface and others may require a waterbed. Information on these additional services may be foundin bulletin 2611/01/05 or contact your nearest Metso’s busi-ness office: www.metso.com/contacts/contact-us/

1.5.5 Rear tilting deviceThe support (38) can be replaced with a rear tilting devicewhich locks the ball against the seat during cooking. Thedevice must be unlocked when operating. See Sections 9and 10.

Operation:

1. The valve is open during filling. The pressure on top thepiston keeps the lock open (the supply pressure is leadto part 74).

2. The valve is closed for cooking. The pressure underneaththe piston push up the rear stem (the supply pressure islead to part 72).

3. During cooking the lock pushes the ball against the seat.This prevents impacts of the vacuum to the ball andimproves the tightness in the beginning of cooking.

4. Before opening of the valve the pressure should be lead ontop the piston to open the lock. If the locking is on whenopening the valve, the seating surfaces of the ball and seatwill be damaged.

Supply air pressure range to the locking cylinder is 4 ... 6 bar.

1.6 Valve approvalThe design of the valve meets the standards and criteria setby ANSI and ASME.

DIN 50049 3.1B material certificates are available for bodyhalves, ball and bonnet. A tightness test certificate is alsosupplied.

1.7 Recycling and disposalMost valve parts can be recycled if sorted according tomaterial. Most parts have material marking. A material list issupplied with the valve. In addition, separate recycling anddisposal instructions are available from the manufacturer. Avalve can also be returned to the manufacturer for recyclingand disposal against a fee.

1.8 Safety precautions

2 TRANSPORTATION, RECEPTION AND STORAGE

Check the valve and accompanying devices for any damagethat may have occurred during transport. Store the valvecarefully prior to installation, preferably indoors in a dryplace. Do not take the valve to the installation site orremove the flow port protectors until it is installed.

The valve is delivered in the open position mounted ontransportation supports.

3 INSTALLATION AND COMMISSIONING

3.1 GeneralRemove the flow port protectors and check that the valve isclean inside and not damaged. Do not remove the trans-portation supports and flow port protection tape untilshortly prior to mounting the valve on the digester.

Fig. 6 Rear tilting device open

CAUTION:Do not exceed the permitted values!Exceeding the permitted values marked on the valve maycause damage and result in uncontrolled pressure release.Damage to equipment or personal injury may result.

CAUTION:Do not remove or dismantle a pressurized valve!Removing or dismantling a pressurized valve leads touncontrolled pressure release. Always release pressureand remove the media from the valve before removing ordismantling it.Protect yourself and the environment from poisonous orotherwise harmful substances.Otherwise, personal injury or damage to equipment mayresult.

CAUTION:Beware of the cutting movement of the ball!Keep hands, other body parts, tools and other objectsaway from the open flow port. When the valve is in opera-tion, the ball functions like a cutter. Shut off the actuatorpressure supply and detach the supply pipes for the dura-tion of maintenance.Otherwise, personal injury or damage to equipment mayresult.

CAUTION:Do not open the valve during cooking!Valve control must be arranged to ensure that the valvecannot be opened during cooking. Otherwise, personalinjury or damage to equipment may result.

CAUTION:Beware of hot valve!The valve body may be very hot during use.Protect yourself against burns.

CAUTION:When handling the valve or the valve package, bear inmind its weight!Never lift the valve or valve package by the actuator, posi-tioner, limit switch or their piping.Always fasten the lifting ropes to the lifting eye bolts, seeFig. 5. Weights are detailed in the table on page 14.Dropping the valve may result in personal injury or dam-age to equipment.

3.2 Mounting the valve on the digester

Lift the valve by the lifting eye bolts, see Fig. 8.

The valve is delivered with the ball in the open position.After any test-runs, make sure that the valve remains in theopen position to protect the ball surface.

To check whether an installed valve is in the open position,ensure that

the arrow on the actuator pointer cover, the groove at the end of the ball stem, the stem key slot,are all parallel to the ball flow port.

We recommend that the chip chute be provided with amanhole approximately 300-500 mm above the valve.

3.3 The actuator

The valve should be installed in a position enabling theactuator to be removed without detaching the valve fromthe digester.

The recommended installation position is with the cylinderupright.

The actuator must not touch the digester structure; vibra-tion may damage it or interfere with its operation.

3.4 CommissioningMake sure there is no foreign matter in the chip chute. If thevalve leaks check adjusting of the tilting device asdescribed in Section 4.7.2 Assembly. If the valve still leakssomething has been damaged in shipment or installationand the factory should be contacted.

After long storage, the gland packing (28) may leak. Tightenit before the valve is brought into use.

4 MAINTENANCE

4.1 General

Although Metso’s Neles valves are designed to work undersevere conditions, proper preventative maintenance cansignificantly help to prevent unplanned downtime and inreal terms reduce the total cost of ownership. Metso recom-mends inspecting the valves at least every five (5) years.

The inspection and maintenance interval depends on theactual application and process condition.

The inspection and maintenance intervals can be specifiedtogether with your local Metso experts. During this periodicinspection the parts detailed in the Spare Part Set shouldbe replaced.

Time in storage should be included in the inspection interval.

Maintenance can be performed as presented below. Formaintenance assistance, please contact your local Metsooffice. The part numbers in the text refer to the explodedview and to the parts list in Section 8, unless otherwisestated.

4.2 Changing the gland packing

If a leak in the gland packing cannot be eliminated by tight-ening it, the packing must be replaced. The actuator can beremoved to facilitate this work.

Remove caps (53). Loosen a little the tilting device nuts (18). Remove nuts (17) and gland (6). Remove ring (34) and old gland packings (28). The

lowest ring (34) need not be removed. Use a suitablepointed instrument for removing the gland packings.Do not damage the seating surface.

CAUTION:When handling the valve or the valve package, bear inmind its weight!

Fig. 8 Lifting the valve

NOTE:When installing the actuator, make sure that the valve/actuator package functions properly. Detailed informationon actuator installation is given in the separate actuatorinstructions.

Observe the safety precautions mentioned in Section1.8 before maintenance!

CAUTION:When handling the valve or the valve package as awhole, bear in mind the weight of the valve or theentire package.

NOTE:When sending goods to the manufacturer for repair, donot disassemble them. Clean the valve carefully and flushthe valve internals. For safety reasons, inform the manu-facturer of the type of medium used in the valve (include material safety data-sheets (MSDS)).

NOTE:In order to ensure safe and effective operation, always useoriginal spare parts to make sure that the valve functionsas intended.

NOTE:For safety reasons, replace pressure retaining bolting if thethreads are damaged, have been heated, stretched or cor-roded.

CAUTION:Ensure that the valve is not pressurized while thegland packing is changed!

8 PZ 70 en 7

Clean the packing counterbore. Push the new packing rings (28) one by one into the

counterbore with the gland (6). Position the cut endsof the rings at a 90° angle to each other and at a 45°angle to the flow port.

Push the outer ring (34) and gland (6) into place andtighten the nuts (17) lightly.

Fasten tight the tilting device nuts (18) and then thenuts (17) and install the cap (53). See Section 4.7.2.

Always check the seal of the gland packings afterinstallation.

4.3 Bearings (5, 22)The ball stem bearing is located in the bonnet (8) under thegland packing rings (28). The bearing is maintenance free. Itis recommended to be dismantled only when the wholevalve is dismantled.

The purpose of the bearing at the rear end of the ball, i.e.the support (38), is to keep the ball at the valve center lineduring operation, allowing a free up-and-down movement.Normally, the support does not need to be inspected orreplaced.

4.4 Body jointIf the body joint leaks, tighten nuts (16) as shown in Table 1.

If the leak continues after the tightening, the valve must bedismantled. Inspect the seating surface and ensure that thebody joint plane is level. Then replace the body gasket (26).See Section 4.7.2.

4.5 Ball and seatingIf the valve leaks, the probable cause is chips between the balland the seat. Before adjusting lifting springs (20), wash andpool the ball surface with a water jet when valve partly open.Operate the valve 2-3 times and retest.

If washing does not help, the valve must be dismantled andcleaned.

If the ball surface is damaged for some reason and causesleakage, the ball can be turned 180° provided that the ballseat is not damaged. A damaged ball seat will destroy theball surface in a short time. The valve must be dismantledfor inspection before turning the ball.

4.6 Dismantling the valve

It is best to dismantle the valve for servicing when it isdetached from the digester. The lower body half can alter-natively be left mounted on the digester. Use the loopsdelivered with the valve for lifting.

Dismantle the valve on a clean, level cardboard or woodenunderlay.

Lower the valve onto the underlay if you haveremoved the whole valve from the digester.

Turn the ball to the closed position.

Detach the actuator using the extractor, seeChapter 6.

Dismantle the upper body half (1). Fasten the lifting strap through the ball and keep it

adequately tightened. Remove caps (53) and the tilting device nuts (18),

disc springs (20) and screws (13). Detach the actuator console (7). Remove the bonnet with gland packings (28) and

bearings (5, 22). Remove the support (38) with extractor screws. Lift the ball out of the body; take care not to damage

the seating surfaces or the stem. Clean all dismantled parts carefully and replace worn

or damaged parts as necessary.

4.6.1 The ballAfter lifting the ball from the body, place it on a clean, softsurface for cleaning. Take special care to clean the ball seat-ing surfaces and the gland packing area. Grind any minorscratches on the ball and packing with 28/20 μm grindingpaste and finish with 7/5 μm paste. Scratches and burrs inthe stem can be ground with fine abrasive cloth of grade400. If there are deeper scratches in the ball or it is mis-shapen, send it to the manufacturer for repair.

4.6.2 Ball seatThe seat (4) is locked in its groove. If the seat is in order andthere is no reason to suspect the condition of the seal (25),the seat need not be dismantled for servicing.

Remove the seat as follows:

First grind down the locking points with a grinder,see Fig. 9.

Open the locking points with a sharp chisel to facili-tate removal, see Fig. 10.

Make sure that the seat slides freely in the groove. Turn the body half upside down and knock it lightly

near the seating edge to make the seat drop out ofthe groove on the underlay.

4.6.3 The bodyClean the body halves carefully and check all seating sur-faces.

The body gasket (26) must be replaced each time the valveis dismantled.

NOTE:Lifting springs are factory preset and excessive tighteningmight damage the ball surface. See Section 4.7.2, Table 2.

CAUTION:Do not dismantle or remove the valve when it is pres-surized!

4.7 Valve assembly

4.7.1 Ball seatTo replace the back seal (25) of the seat (4), proceed as fol-lows:

Cut the ends of the seal band to give a tight sealagainst the edges of the groove where the two endsoverlap, see Fig. 11.

Place the seat into the upper body half and lock it atthe four points at 90° intervals, see Fig. 12.

Do not lock the seat too tight; it must be allowed toslide in the groove.

4.7.2 Assembly Place e.g. corrugated cardboard in the body to pro-

tect the ball during the lifting. Fasten the liftingstraps through the flow port.

Lift the ball into the lower body half with the stemfirst through the bonnet opening. Center the ball inthe flow port. Leave the ball suspended by the liftingstraps.

Mount the support (38) and the new spiral gasket(39).

Push the bearing (5) over the stem to match the lock-ing notches with the locking ring stops at the butt ofthe ball stem.

Slip the bearing (22) along the stem. The bearinglock notch must match with the locking groove onthe bonnet (8).

Mount the bonnet (8) and the new bonnet gasket(9).

Push the ring (34) and the new gland packings (28)one by one into the packing groove with the gland.Position the cut ends of the rings at a 90° angle toeach other and at a 45° angle to the flow port.

Set the outer ring (34) and the gland (6) into placeand tighten the nuts (17) lightly.

Set the body gasket (26) in place. The gasket must bereplaced each time the valve is dismantled.

Install the tilting device. Replace the bearings (24)and ring (41) of the console (7). Slide the ring (41)onto the stem.

Turn the screws (13) into the valve lugs, lock themwith lock nut (13a). Tighten the disc spring packs (20)with nuts (18).

Loosen the ball from the lifting straps and removethe straps.

Make sure that the ball is in the center of the flowport by measuring the distances from the ball sur-face to the groove of the body joint plane.

Lift the upper body half into place in the originalposition. See that a gap of about 5 mm (0.2") is left inthe body joint when the body half is resting on theball.

Tighten the body joint nuts (16) as shown in Table 1.

Mount the actuator, see Chapter 5. Measure the distance "B", See Fig. 13.

Feed compressed air into the actuator via the pres-sure regulator, see Fig. 14.

If the actuator cannot turn the ball with the pressureindicated in Table 2, depressurize the actuator andloosen both tilting device nuts (18) by 90°. Whennecessary, continue loosening the nuts 90° at a timeuntil the valve turns at the pressure indicated in thetable, see Fig. 15. Measure the distance "A", seeFig. 16.

The measure "C" is the correct thickness of thewasher. If necessary, thin the washer. See Fig. 17.Tighten the screws, keeping them in horizontallybalance.

Tighten the nuts (18). Fill the cavities with Mobilplex 47 or equivalent

grease. Mount the caps (53). Fasten tight the gland packing nuts (17). Always

check the tightness of the gland packings afterinstallation of the valve.

5 INSTALLING THE ACTUATORMake use of the separate actuator instructions.

Make sure that the stem end is clean and free fromburrs.

Select the stem key slot that indicates that the valveis in the extreme position when the valve is closed.

Turn the studs into the actuator before sliding theactuator onto the stem.

Slide the actuator into position carefully. Adjust the open and closed position limits.

5.1 Adjusting open and closed positionsThe open and closed position limits of the valve are adjustedwith the stop screws on the actuator, see Fig. 18.

Adjusting the closed position:

Using a soft pencil, draw two lines on the top surface of theball, the first at G1 and the second at G2 distance from theedge of the ball flow port, see Fig. 19 and Table 3.

Adjust the closed position stop screw so that the endof the G1 line is just visible directly under the edge ofthe body flow port when the valve is closed, see Fig. 20.

Adjust the limit switch's close position, limit switch isactivated when the end of the G2 line is just visibledirectly under the edge of the body flow port, seeFig. 21.
